tubes or envelops, which construction shall be strong andsolid and shall contaotfwith the ends of the active material vormaterial adapted to become active andwith the lends of thetubes and shall fill -the endsfof the tubes, although these ends are unevenror at` different levelsvin the respective tubes, so that trimming and fitting with their disadvantages are not required. Otherobjects of` the invention will appear from the" following description which will begiven vin conf nection with the accompanying 'drawings forming part hereofand in 'which- Figure l', is a side elevation ofl a part ofm a plate or electrode embodying features of the invention. t Fig. 2, is an inverted plan of the same. Fig. 3, is a transverse sectional view'drawn to an enlarged scale and illustrating the end construction, and

Figs. 4 and 5, are sections respectively on the lines 4--4 and 5-5 of Fig. 3.

In the drawings the metallic conducting rods l, surrounded by active material or material adapted to become active 2, inclosed in' insulating slotted or perforated tubes or retainers 3, are features of construction of well known elements or plates.

The end construction of the invention consists of a poured connecting bar 4, fitting in equalities in the lengths of the tubes 3,y and contacting with the ends of the tubes as at 5. By a poured bar is meant that-the ends `the bar is poured itcontacts with the ends ofthe tubes 3, and of the rods 1,-are ary ranged in amold and the bar 4, is made by pouring molten metal into the mold. 'Inequalities in the lengths of the tubes 3, means that they end atY different levels as indicated by the line a-b, in Fig 1,- but since of all thetubes as at 5, and so it is unnecessary to trim the tubes. Moreover such a bar 4, 1s cheap and easy to'make.l Portions 6, of

, the bar fill the ends ofy thetubes and fit 'inequalities in the ends of activematerial or materlal adapted'to become active 2, and

lcontact with these ends although theyare at dierent levels. due for instance 'to some of the material 2, falling out of the ends of the tubes which is a matter of common occurrence. The. end construction is therefore solid and strong and of good electrical con-- ductivity. The ends of the rods. 1, merge into the bar 4, and thereforer thesev ends may beat different levels.l 1 What I'claim is: l 1. In a storage battery plate or electrode, including metal rods surrounded with active' material or material adapted to become active inclosed in perforated insulating tubes an end construction consisting of a poured connecting bar fitting inequalities in the lengths of the tubes and contacting with the ends ofthe tubes and portions of said bar filling the ends'ofthe tubes and fitting inequalities in the ends ofthe active material ormaterial adapted to become active and contacting therewith and said bar and the ends of said rods being joined by merger, substantially as described'.

2. In the manufacture of a storage battery plate or electrode including metal rods 1 surrounded with active material or material adapted to become active inclosed in perforated insulating tubes or envelops, the method of making and joining an end bar which consists in applying it while molten directly to the rods and tubes and material,

whereby the rodsand end bar are connected. 95
